- The greatest common factor, or GCF, can be factored out of a polynomial. Checking for a GCF should be the first step in any factoring problem.
- Trinomials with leading coefficient 1 can be factored by finding numbers that have a product of the third term and a sum of the second term.
- Trinomials can be factored using a process called factoring by grouping.
- Perfect square trinomials and the difference of squares are special products and can be factored using equations.
- The sum of cubes and the difference of cubes can be factored using equations.
- Polynomials containing fractional and negative exponents can be factored by pulling out a GCF.
